j ports for electrical apparatus and more particularly Vto a means for mounting relays.

It is an obj ect of the invention to mount a relay or other piece of apparatus upon a plate which has attached to one side a num ber of jacks for receiving corresponding plugs on a rack, and has on its other side a support upon which the relay or apparatus rests.

Another object of the invention is to improve a cover, for apparatus so that it may be snapped over a support to completely house the apparatus, and to protect it from dirt and dust. j

More specifically, the invention relates to a means for mounting apparatus on a rack, this means comprising a mounting plate or frame provided with a plurality of jacks or terminals to receive plugs which are provided on the mounted apparatus, this plate having attached thereto a three-sided re` ceptacle upon which the weight of the apparatus rests. This receptacle is so shaped that the apparatus fits snugly within the same and its sides are furthermorey cut away leaving the adjusting means for the apparatus readily accessible. A cover is provided with retaining springs which are snapped over studs integral with the sides of the receptacle and thus securely held in place.

In the drawings, Fig. 1 shows a preferred embodiment of the apparatus mounting partly in section, the yimprovedcover being withdrawn as in the apparatus itself, to disclose the details of these parts, while Fig. 2 is a plan view of the apparatus as it appears when housed wit-hin the receptacle and cover, and Fig. Sis an end view of the apparatus and the housing.

Referring to the drawings in detail, a mounting plate 1 has securely attached to its one face a U-shaped terminal supporting connecting block 2 upon which is mounted aplurality of terminals or jacks 3 which are accessible from the other side of the mounting plate 1 through an opening 4 provided for this purpose. A threesided supporting receptacle 5 is attached to `the opposite face of the mounting plate 1 and projects perpendicularly therefrom. This receptacle 5 supports the weight of a relay 6 which is shown as ofthe type disclosed in Patent No. 1,523,423, granted to CASIGAND SUPPORT FOR` ELECTRICAL APPARATUS.

may be any other apparatus, the invention notl being limited to any specific' device. The supporting receptacle has its sides cut away as shown in the drawing at 7 in order that the relay adjusting means 8 may be readily accessible while therelay is mounted on the rack, rIhe vertical sides of the receptacle 5 are also bulged outwardly at 9 where they join the horizontal portion of the support, this construction conforming -with the relay base 17 which isl slightly wider than the relay 6 itself. A plurality of plugs 10 secured to the relay base 17 are provided for insertion into-the jacks 3 secured to the mounting plate or frame 1, and cooperate therewith to hold the relay in place while Yon the receptacle 5. The plugs 10 may serve as terminals for the windings and contacts of the relay and by contacting with the jacks 3 may connect the relay into any suitable circuit with which the jacks may be associated.

A metallic cover 11 having a projecting handle or flange 12 is so constructed as to permit it to slide over the top of the supporting receptacle 5. Metal strips 1.3 provided with Ushaped flanges 14 are attached to the interior of the sides of the cover 11. Leaf springs 15 are riveted to the flanges 14 of the metal strips 1B and are therefore similarly spaced from the interior surface of the cover 11. When the cover 11.is slid over the supporting receptacle 5, the flanges 14 rest upon the sides of the receptacle, whereas the leaf springs 15 ride up over studs 16 on the receptacle 5 and snap in place beyond these studs, thereby securely holding the cover 11 in place.

The bulged formation of the receptacle 5 permits the sides ofthe cover 11 to align themselves with the wide support, so that the entire housing when assembled, has smooth uniform sides and therefore pre sents a neat and compact appearance.

Vhat is claimed is: A

1.`An apparatus mounting comprising a plate having` mounted thereon a trough-like receptacle for supporting apparatus, said receptacle being provided with studs on the interior surface of its sides and an openended cover adapted to slide over said receptacle, said cover being provided withflanges and internally mounted resilient members cooperating with the said studs on said receptacle for securely holding said cover in place, said elements comprising the receptacle cover and fastening means being so constructed" and arranged that when the cover is placed imposition it will exert no strain on the apparatus placed in said receptacle.

2. A mounting for delicately adjusted electrical apparatus, comprising a mounting 10 plate, an open ended'channel shaped sup-
